COCKIOR FAUCETS WITH STOP VALVES.

Application mea nay e,

To all whom 'it may concer/n:

Be it known that I, PETER R. RICHARDS, a citizen of the United States,residing at Cleveland, in the county of Cuyahoga and State of Chio, haveinvented a certain new and useful Improvements in Cocks for Faucets withStop Valves, of which the' followreference being had to the accompanyingdrawings. I

'Ihis invention relates generally tococks and faucets and moreparticularly to a stop valve arranged in the stem of said cock or faucetfor the purpose of cutting off the fiow of water while the main valve isbeing re paired or replaced.

The object of the invention is to. provide a simple and highly efficientconstruction and arrangement of cut-olf va ve which can be arranged inthe main stem of the cock or faucet and which lcan be quickly and easilyoperated to open or shut oli' the supply of water. Another object of theinvention is to provide a novel construction of packing means wherebyall danger of leakage at the point where the stop valve is arranged isavoided. A still further object is to so construct the valvc as to avoidhammering and at the same time provide for proper setting of the stopvalve.

Vith these and various objects in view the inventionconsists lin thenovel features of construction and in the manner of combining orarranging the several parts, all of which will be fully describedhereinafter and set forth in the appended claims.

' In the drawings forming a part of this specification Fig. 1 is avertical longitudinal sectional view of a coc-k or faucet con' structedin accordance with my invention,` the stop valve being shown open; Fig.2 is a lsimilar view, the stop valve being shown closed; Fig. 3 is adetail sectional view onthe line 3-3 of Fig. 1 and Fig. 4 is a detailsectional view of a slightly modified construction of valve. In thepractical embodiment of my invention I employ a casing A having arearwardly extendlng stem portion A and a forwarrdly extending spoutportion A2. The casing is formed with a subdividing partition or diaphraB which is apertured as usual and provi ed with a seat upon which seatsthe valve D secured to the lower end of the stem E, this stem beingenlarged and threaded so as to engage corre- Ing is a full, clear, andexact description,`

sponding threads in the casing and the upper reduced end of the stem'll2is provided with the operating handle F and the nut or gasket' G servesto hold the valve in place and alsol retain the usual form of packingand stop devices. `The elements thus far described are of the usual 0rordinary construction except that the stem portion A is slightly longerthan the usual cock or faucet stem. At the point where the casing properand stem meet there is provided a partition or diaphragm H havinganopening I cut therein and shaped to provide a suitable seat for thevalve K which is externally threaded and""screws into thethreadedenlargement L and partition The stem is tapped at this point to receivethe protecting cap M. The valve K is formed with an upwardly extendingstem portion K which is bifurcated at its upper end as shown at K2 inorder to receive a screw driver or other tool for the purpose of turningthe valve up or down as desired .and this stem works through aliapertured plate N which is threaded into the threaded opening tapped inthe upper side of the stem and this apertured plate N.; also holds inplace the concentric fiber wash# ers O` and O', the washer O beingfitted close to the stem K while the washer O2 is arranged outside ofthe washer C and has its' outer edges in proximity to the threads of theopening tapped in the stem. The apertured plate N is formed with socketsN in the upper face thereof to receive a suitable wrench for Ythepurpose of screwing and unscrewing the plate in place.

It will be understood that the main portion of the cock or faucet isconstructed and assembled in the usual manner. The valve K is theninserted and the fiber washers placed in position. upon the stein K andwithin the threaded opening tapped in the upper side of the hollow stem.After `the washers have been properly arranged the apertured plate NL isfastened in position and the valve K can be turned up or down as desiredand then the `cap M is secured in place ,and the device is complete.When the cock or faucet is in use the valve K will of course be open asshown in Fig. 1. When it is desired to repack the main valve or torepair or replace the same the cap M is removed and the valve K screweddown so as to close the opening I. The flow of water is thereby cut loffand the repair or replacecan be utilized to regulate the Volume ofthewater passing through the cock 4or faucet and this feature is valuableparticularly in eases Where a number of cocks are connected to the samepipe at different levels. With the ordinary cocks and .faucets when thelowermost cock or faucet is fully opened the vflow through the uppercocks is materially reduced. By adjusting the valve K in the lowermostcock and the upper succeeding cocks this can be avoided.

By the employment of two fiber washers concentrically arranged I preventall leakage inasmuch as the inner washer O prevents leakage around thestem and the upper washer O prevents leakage around the edge of theopening.

In case there should be any inaccuracy in the boring of the valve seat Iand the proper centering of the valve thereon it can be avoided byproviding the valve K with a ball or sphere K* which is held in a socketK* formed .in the end of thevalve and inasmuch as this ball or sphere isfree to turn itA will always iind a proper seat irrespective It willthus be seen that I provide-an exeeedingly simple and highly etiicientdevice in the form of a stop valve which is arranged entirely within thestem of the cock or faucet and a11without materially increasing thedimensions of said valve.

Having thus described my invention, what I claim 1s:

1. A cock or `faucet having a partition formed 1n the stem thereof, saidpartition being provided with a valve seat, said stem being tapped inalignment with said seat, and also having a threaded enlargement, a stopvalve externally threaded and having its inner end adapted to seat uponthe valve Seat and its outer end extending outwardly a considerabledistance, packing surrounding the upwardly projecting end of said stopvalve, a disk or plate securing said packing in place and a cap screwedinto the faucet stem and protecting the end of the stop valve stem andmaintaining the disk in place.

2. A cock or faucet stem having a partition therein said stem beingtapped through the upper side and through the partition and providing avalve seat in said partition, a valve having a seat, a threaded portionand a stem, concentric washers surrounding said stem, a disk or platefor holdingsaid Washers in place and a cap screwed into the top of thestem and protecting the upper end of the stop valve.

' In testimony whereof, I hereunto aiix my signature.
